Additional Notes
- The 1990 Mitsubishi Montero accommodates multiple speaker sizes across different locations, with the dashboard housing 4-inch midrange units while door and rear positions accept larger formats.
- Dashboard speakers in this application are limited to 4-inch midrange drivers, which typically focus on vocal and instrumental frequencies rather than delivering full-spectrum audio output.
- Both front and rear door panels offer compatibility with 5.25-inch formats, allowing for either midbass drivers that emphasize lower frequencies or full-range speakers that attempt to reproduce broader sound spectrums.
- The presence of 6.5-inch mounting locations in front door panels, rear areas, and rear side panels suggests potential for enhanced bass response compared to smaller speaker sizes.
- Multiple mounting options at similar locations may indicate factory variations or aftermarket modification possibilities, though installers would need to verify specific mounting depths and adapters for each position.
- Full-range speakers in the 5.25-inch and 6.5-inch positions could provide adequate sound without additional tweeters, while midbass configurations would typically require separate high-frequency drivers for balanced audio reproduction.
- The single DIN radio opening follows standard head unit sizing from this era, maintaining compatibility with most aftermarket receivers without requiring dash modifications.
- Larger 6.5-inch speakers generally move more air than their 5.25-inch counterparts, potentially offering improved low-frequency extension and overall output levels in comparable enclosures.
- Midrange-only dashboard speakers might benefit from pairing with component systems in door locations to achieve fuller frequency coverage throughout the cabin.
